The conserved mass and angular momentum of the solutions of the
above field equations can be calculated through the use of the
substraction method of Brown and York [1]}. Such a procedure
causes the resulting physical quantities to depend on the choice
of reference background. A well-known method of dealing with this
divergence for asymptotically AdS solutions of Einstein gravity is
through the use of counterterm method inspired by AdS/CFT
correspondence [2]}. In this Letter, we deal with the
spacetimes with zero curvature boundary, \(R_{abcd}(\gamma )=0\) ,
and therefore the counterterm for the stress energy tensor should
be proportional to \(\gamma ^{ab}\) . We find the suitable
counterterm which removes the divergences of the action in the
form (see also [3]})
\(I_{ct}=-\frac{1}{8\pi }\int _{\partial \mathcal {M}}d^{3}x\sqrt{-\gamma }\left(-\frac{1}{l}+\frac{\sqrt{-6V(\Phi )}}{2} \right).\)
